The Harken 40.2STC Self-Tailing Radial Winch combines powerful two-speed performance with premium chrome construction for smooth, efficient sail handling under load. Featuring Harken’s proven Radial drum technology and integrated self-tailing system, it delivers exceptional grip, reduced rope wear, and reliable trimming performance for racing and cruising yachts.

The Harken 40 Self-Tailing Radial Winch — 2 Speed Chrome - 40.2STC is engineered for sailors who demand high-load sail handling performance with precise control and long-term durability. Built around Harken’s renowned Radial drum technology, the drum surface is specifically shaped for optimal rope handling, using diagonal ribs instead of abrasive textures to maximise grip while significantly reducing line wear.

The integrated self-tailing mechanism allows a single crew member to trim or hoist sails efficiently without requiring constant tailing assistance. Combined with the two-speed gearing system, sailors can transition smoothly between fast line retrieval and powerful high-load trimming, improving control and reducing fatigue during demanding manoeuvres.

Constructed with a premium chrome finish, the 40.2STC delivers outstanding corrosion resistance and a refined appearance suited to both performance yachts and premium cruising boats. Its durable construction and efficient mechanical advantage make it ideal for handling halyards, sheets, and control lines under significant load.

Whether racing competitively or cruising offshore, the Harken 40.2STC provides smooth operation, trusted reliability, and efficient sail management in a compact, high-performance package.
